ON THE PREDICTION OF THE FATIGUE LIFE OF RAILS

This paper introduces a methodology for calculation of the fatigue life of rails in service. Increased wheel loads has increased fatigue-related problems. A service environment is represented by means of an environmental load spectra which is then converted to stresses at the rail. Although the paper is limited to flexural rail stresses, the methodology can be extended to other states of stress. Once the spectra is established, rail life is calculated by means of Miner's linear cumulative damage theory. Along with showing the detrimental effect of increased wheel loads, the need for matching rail size to loads is necessary to minimize rail defects.
